it known that l, MAX lls'r'siu., a citithe llnited States, and L. resident of provementin lrireless paratus, of which the followlleceivingj p inoj is a snee mation,

My inviention relates to Wireless receiving' apparatus and more especially to inountinn's for vacuum tubes employed in such apparatus.

ln its broad aspect, an object of my invention is to provide a mount-ing` for vacuo-1n tubes which effectuallv protects the 'tubes from local shocks or disturbances.

lli/lore specifically, another obiect of my invention is to pro 'fle means which limit the motion of hei-va enum-tube when force is exerted thereon, as obtains during); the insertion of a vacuum tube therein, said limiting' means also serving' as terminal support for the flexible leads extending from the base socket. .A further object ofmy invention is to provioe apparatus of jthe class described which is of simple, Compact, anc` rugged design and which is susceptible of inexpensive quantityproduction methods of manufacture, the several parts thereof being` readily manufactured in existing` automatic machinery and being readily assembled with a minimum expenditure of time and money.

lt is Well known that, When a vacuum tube is subjected to a sudden shock, the several elements contained Within the tnbe are set to vibrating` according; to the natural periods thereof. The vibration of the elements causes variations inl the relative spacing; thereof and, consequently, alters the characteristics of the tube, thereby resulting' in noisy and ineiiicient operation.

According' to my invention,` l provide a shocl-absorbinn` vcradle for the tubes, Whereby the effects of local vibration are eliminated, and whereby a terminal support is provided for the flexible conductors leadingfrom the base socket. rllhe structure for aecomplishinn` the above mentioned results comprises a base-socket panel having` opposite ends resiliently secured to iinedsupports. ln a preferred form of embodim it of my invent-ion, the fixed supports are provided by a main operations panel. which also controls the operation of the tubes, and

Serial No. 5921234.

a sub-panel, unich also provides a support for terminal connectors. The sub-panel may be rigidly secured to the main operating` panel in a manner hereinafter set forth, and the 'Whole structure is removably positioned in cabinet with the control panel constitutint;` a closure therefor.

lilith these and other objects and other applications in View, my invention further consists in the details of construction and arrangement hereinafter described and claimed and illustrated in the accompanying` drawing, wherein Figure l is a vertical vlongitudinal sectional view of a Wireless receiving cabinet embodying,` my invention, the sectionbeing talten on the line .le-l of Fig. 2, and

Fig. 2 is horizontal sectional view of the struc :e shovvn in Fig. l, the section plane being` indicated by the line lI-Il of Fig. l.

ln the illustrated form of embodiment of my invention shown in the drawing, a cabinet l is provided which is open in front and which is provided with perforations 2 in a rear yall 3 thereof, the perforations 2 removably receiving' external circuit terminals 1 1 for the apparatus contained Within the cabinet l. ifi-recess to the interior of the cabinet l through the outside thereof is provided through an opening' 5 in the top.

A main panel which constitutes a closure for the front end of the cabinet l and Which also serves as a control panel, has rigidly secured, in spaced relation to its inner surface, a sub-panel 7, the tivo panels being,` connected by means of supporting rods S. rlhe length of the suliliorting rods 8 is such as to position the sub-panel 7 immediately adjacent to 'the rear wall 3 of the cabinet l. rlhe plurality of terminal connectors lare carried by the sub-panel 7 and extend through the perforations 2 iin the rear Wall 3, thereby providing` connections accessible from the outside of the cabinet l.

i vacuum-tube base-socket panel 9, carrying a plurality of socket devices ll, having flexible terminal leads l2, is horizontally positioned in its place between the two panels G and "t" iu such manner as to provide a support for tubes (not shown) which are normally inserted through the opening` 5, in the top side of the cabinet l. rEhe panel 9 may be resiliently supported by means of a pair of rubber straps 13 and le which are secured to opposite edges thereof by means cured to supporting blocks 18 by means of clamping members 19.

The extensions 1G and 17 have just sutiicient strength to support panel 9, and apparatus carried. thereby, hence providing` an extremely 'flexible connection. Such construction, however, has a disadvantage that when a torce is brought to bear upon the vacuum-tube socket panel 9., by the insertion ot a tube in one otl the socket devices 11, the material of the resilient extensions 1G and 17 may be stretched beyond its elastic limit, thereby destroying the resiliency ot the mounting.

The foregoing undesired result is overcome, in my invention, by the provision ot stationary bars 21 and 22 which are disposed as to limit the displacement ot the base socket panel 9 to a safe amount. The bars 21 and 22 are dispose.Y 'directly beneath the outer edges of the base socket panel 9 and have their opposite ends secured to the blocks 18 by means ot screw connectors 23. The bars are also provided with a number of stationary electrical connectors to which the flexible leads 12 ot the socket device may be secured. Hence the bars 21 and 22 also serve as terminal supports.

A pair ot filament rheostats 25 and 2S are secured to the inside surface ot the control panel 6 directly beneath the base-socket panel 9 and may be operated by `knobs 27 and 28, respectively, which are mountec on the outer surface ot the control panel (l. One or more telephone jacks 29 of Well known design are mounted in the control panel G directly beneath the rheostats and 26. In order that the description ot my invention may be simplified, I have omitted the circuit connections contained in the apparatus and also such additional apparatus as was not essential to a clear understanding ot my invention.

In summary, it will be seen that I provide a resilient mounting for fragile vaciuun-tube structures, whereby protectionis afforded against external shocks or disturbances. In addition, means are provided which not only limit the displacement ot the resilient mounting panel 9, carrying the tubes (not shown) to a predetermined amount but also provides a fixed support t'or the tlexlible leads 12 of the socketdevices 11.

Vfhile I have described a certain form ol embodiment oi my invention in detail and While l have pointed out certain ot the most obvious principles and purposes thereot, I do not intend that the language employed in the following claims shall be limited to the precise features described, but I intend that claims shall be construed to cover all combinations which are tairly inchuV ed in the language thereotI when read in connection with the prior art, regardless ot the details and functions mentioned in the description or illustrated in the drawing.

I claim as my iinrention:

1. In combination, a pair ot vertically positioned panels, means for rigidly secursaid panels Iin such spaced relation as to provide an open space therebetnveim, a basesocket member horizontally positioned in said open space and having opposite ends resiliently secured to adjacent panels, a pair ot members having` opposite ends rigidly secured to said panels and l'iorizontally positioned immediately adjacent to the under surta-icc ot said base-soclcet member to limit the motion thereof to a predetermined amount, and electrical connectors mounted on said members.

2. In combination, a pair of vertically positioned panels, means tor rigidly securing id panels in such spaced relation as t0 provide an open space therebetween, a basesocket member horizontally positioned :in said open space and having opposite ends `liently secured. to adjacent panels, condcvices having flexible terminal leads carried by said base member, a pair ot` members haring opposite ends rigidly secured to said panels and horizontally positioned immediately adjacent to the under surface ot said base-socket member to limit the displacement of the base member, and electrical terminal connectors mounted on one both ol said pair ol" members.

In combination, a base socket member, a pair et strips of resilient material secured to opposite edges there it and having tree end portions extending therefrom, means for scc-ui" said tree end portions in such meijer as to cause said base-socket men'iber yntly mounted, means for limitto be res .i ing the motion of said base socket in a predetermined direction, and electrical terminal connector. .tarried by said limitingmeans.

ln testin'iony whereof, I have hereunto subscribed my name this 30th day ot Septomber 1922.
